Exodus 30:29-33

You shall also consecrate them, so that they may be most holy; whatever touches them shall be holy.

And you shall anoint Aaron and his sons, and consecrate them, so that they may serve as priests to Me.

Furthermore, you shall speak to the sons of Israel, saying, ‘This shall be a holy anointing oil to Me throughout your generations.

It shall not be poured on anyone’s body, nor shall you make any like it in the same proportions; it is holy, and it shall be holy to you.

Whoever mixes any like it or whoever puts any of it on a layman shall be cut off from his people.’ ” The Incense
